Hubble Space Telescope Image of the
Planetary Nebula BD+30 3639
The Hubble Space Telescope Image of BD+30 3639 shows a
ring of gas at 30,000 degrees Celsius. This ring was
ejected by a dying red giant star, and is now heated by
ultraviolet radiation from the central star.
Scale: Image is 6.6 arcsec
on a side. (1 arcsec = 230 billion kilometers at a
distance of 5000 light years.)

Infrared Image of the Planetary
Nebula BD+30 3639
This infrared image at a wavelength of 2.2 microns
shows radiation from dust grains at a temperature of
-170 degrees Celsius. The dark red ring in the center
of the image is an instrumental artifact.
Scale: Image is 6.6 arcsec
on a side. (1 arcsec = 230 billion kilometers at a
distance of 5000 light years.)

Optical-X-ray Comparison of
Planetary Nebula BD+30 3639
The hot gas cloud seen in the X-ray image (at right)
fits inside the rim of cooler gas seen in the optical
image.

Optical/Infrared/X-ray comparison
for the planetary nebula BD+30 3639
The planetary nebula was formed when a ring of gas and
dust was ejected by a dying red giant star about a
thousand years ago. The optical (left) shows gas in the
ring that has been heated to 30,000 degrees Celsius
that has been heated by ultraviolet radiation from the
central star. The infrared image (middle) shows
radiation from dust grains at a temperature of -170
degrees Celsius. The Chandra X-ray image (right) shows
a 3 million degree Celsius cloud that appears to fit
inside the rim of gas and dust seen in the optical and
infrared images.
